Liquid Reservoir

Liquid Reservoir is a building that allows for 5 ton of Liquid storage.

It can connect to a Liquid Intake Pipe and a Liquid Output Pipe, and is useful as a power-free in-line buffer, since it also eliminates need for intermediary Liquid Pumps. At least one segment of Liquid Intake Pipe must be connected for Liquid Reservoir to work. The Liquid Output Pipe is optional.

Reservoir can be disabled by Duplicant. Alternatively it can be built upon a horizontal Mechanized Airlock which is controlled by automation signals. When disabled in either way, it stops outputting its content, while still accepting the input.

Be aware the Reservoir can overheat depending on the environment it is sitting in, and has a low initial overheat temperature of 75 °C. It's best to build them out of Gold Amalgam or Steel if you are dealing with high temperature environments.

Possible Bug
Contents inside the reservoir only exchange heat with the tile directly below the reservoir's output port (confirmed in ). It will especially not heat up or cool down the reservoir itself (although this may be a bug). If the tile is a vacuum (by placing an Airflow Tile or Mesh Tile and removing any gas or liquid that would flow into it), then there will be no heat exchange at all.

Not Entirely Perfect Insulation
Other than the above peculiarity, the Reservoir appears to perfectly insulate its contents from its surroundings and vice versa, e.g. very hot or very cold liquids can be stored in a Copper reservoir without them heating up or cooling down their surroundings.

However, in actuality, the Reservoir still exchanges heat with its contents, albeit at a rate lower than Insulated Tiles made of Ceramic. This can be observed by having the Reservoir hold liquids with particularly volatile heat properties, like Liquid Oxygen.

Tips

 * It is more energy-efficient to keep your liquids in reservoirs, since it saves on pumping.


 * A full surface Water (or Polluted Water) tile weighs 1000 kg, so one reservoir can hold approximately 5 tiles of water while taking up 6 tiles of space.
 * However, liquid can also fill the tiles a reservoir inhabits, allowing approximately 11000 kg of water to fit into 6 tiles of space.
 * This inefficiency decreases with Crude Oil, and storing Petroleum in reservoir is actually more space-efficient.
 * Tile-filling liquid storage also prevents ease of access by Duplicants.
 * If a liquid reservoir is submerged in Chlorine, any germs on its contents will be quickly killed. This is a good way of quickly eliminating Food Poisoning germs from your lavatory and sink facilities.
 * A common set up is to use three sequential Liquid Reservoirs built upon Mechanized Airlocks. These airlocks are connected to a Cycle Sensor that sends Green Signal in first half circle and Red Signal in second half circle. The first and third airlock is simply connected to the sensor, while the second airlock is connected via a NOT Gate. With this setup, the Polluted Water will stay in each Liquid Reservoir for half circle and any germs will be killed.


 * Liquid Reservoirs average out the temperature of each liquid pumped into it (thus smoothing out temperature spikes/differences from the input liquid). This allows, for example, for much easier temperature control if a Liquid Pipe Thermo Sensor is placed on the output pipe.
 * When feeding Metal Refineries with liquid from these reservoirs and then dumping the heated liquid back into the latter, it may be wise to use regular piping so that the liquid can cool off along the way.
 * That is, assuming that you are not resorting to cooling the output liquid.
